IMPROVEMENT IN GAS-BURNERS.

Specification forming part of Letters Patent No. 137,964, dated Ap1i115,1873; appication filed February 5, 1873.

To all whom it may concern:

Be it known that I, I. W. SEALER, of Brooklyn, county of Kings and Stateof New York, have invented certain new and useful Improvements inGas-Fixtures, of which the following is a specification:

The nature of my invention relates to the construction of a gas-burner;and consists in making an aperture inthe base of the tip, on each sideof the flame, through which issues a small jet of gas, which whenignited heats the air as it ascends to the flame, and causes a perfectcombustion to take place just at the point of the tip where the flameissues, and prevents the flickering of the flame; it also consists in anadjustable collar for regulating the size of the small jets, as will bemore fully set forth hereafter.

Figure 1 represents a side elevation of my burner. Fig. 2 is a side viewof the tip, showing the aperture. Fig. 3 is a sectional view.

00 represents a pillar of ordinary construction, in the top of which isscrewed the tip I). In the bottom of this tip, upon each side, atthrough which the are formed two slots, holes, or apertures, c, of anysuitable kind, through which the two small jets 'i issue and extendupward toward the flame, heating the upward current of air before itreaches the flame.

The flickering of the flame is not produced, a

as is generally supposed, by the uneven pressure of the gas, but by theupward tendency of the heated atmosphere, causing an uneven temperature,in which the combustion takes place, and hence the flame is unsteady andflickers; but by heating the air before it reaches the flame thetemperature is always kept even, and a perfect combustion of the gastakes place at the very point of the tip, causing not only a morebrilliant, but a steady and even flame. Over the top of the pillar isscrewed an adjustable collar, 0, by which the size of the apertures isregulated, so that the jets i can be controlled at will. This collaralso controls and regulates the angle at which the jets issue from thetip.

Having thus described my invention, what I Q and desire to secure byLetters.

claim as new, Patent, is-

The pillar a, having adjustable collar e, in combination with the tipI), provided with the aperture 0, substantially as shown and described.I

In testimony that I claim the foregoing as my invention I hereunto affixmy signature.
